雅思阅读模拟试题及答案解析(4)
雅思阅读模拟试题及答案解析（4）Selling Digital Music without Copy-protection Makes SenseA. It was uncharacteristically low-key for the industry’s greatest showman. But the essay published this week by Steve Jobs， the boss of Apple，on his firm’s website under the unassuming title “Thoughts on Music” has nonetheless provoked a vigorous debate about the future of digital music，which Apple dominates with its iPod music-player and iTunes music-store. At issue is “digital rights management” (DRM)—the technology guarding downloaded music against theft. Since there is no common standard for DRM， it also has the side-effect that songs purchased for one type of music-player may not work on another. Apple’s DRM system， called FairPlay， is the most widespread. So it came as a surprise when Mr. Jobs called for DRM for digital music to be abolished.B. This is a change of tack for Apple. It has come under fire from European regulators who claim that its refusal to license FairPlay to other firms has “locked in” customers. Since music from the iTunes store cannot be played on non-iPod music-players (at least not without a lot of fiddling)，any iTunes buyer will be deterred from switching to a device made by a rival firm， such as Sony or Microsoft. When French lawmakers drafted a bill last year compelling Apple to open up FairPlay to rivals， the company warned of “state-sponsored piracy”. Only DRM， it implied， could keep the pirates at bay.C. This week Mr. Jobs gave another explanation for his former defence of DRM： the record companies made him do it. They would make their music available to the iTunes store only if Apple agreed to protect it using DRM. They can still withdraw their catalogues if the DRM system is compromised. Apple cannot license FairPlay to others， says Mr Jobs， because it would depend on them to produce security fixes promptly. All DRM does is restrict consumer choice and provide a barrier to entry， says Mr Jobs； without it there would be far more stores and players， and far more innovation. So， he suggests， why not do away with DRM and sell music unprotected？“This isclearly the best alternative for consumers，” he declares，“and Apple would embrace it in a heartbeat.”D. Why the sudden change of heart？ Mr Jobs seems chiefly concerned with getting Europe’s regulators off his back. Rather than complaining to Apple about its use of DRM， he suggests，“those unhappy with the current situation should redirect their energies towards persuading the music companies to sell their music DRM-free.” Two and a half of the four big record companies， he helpfully points out， are European-owned. Mr Jobs also hopes to paint himself as a consumer champion. Apple resents accusations that it has become the Microsoft of digital music.E. Apple can afford to embrace open competition in music players and online stores. Consumers would gravitate to the best player and the best store， and at the moment that still means Apple’s. Mr Jobs is evidently unfazed by rivals to the iPod. Since only 3% of the music in a typical iTunes library is protected， most of it can already be used on other players today，he notes. (And even the protected tracks can be burned onto a CD and then re-ripped.) So Apple’s dominance evidently depends far more on branding and ease of use than DRM-related “lock in”.F. The music giants are trying DRM-free downloads. Lots of smaller labels already sell music that way. Having seen which way the wind is blowing， Mr Jobs now wants to be seen not as DRM’s defender， but as a consumer champion who helped in its downfall. Wouldn’t it lead to a surge in piracy？ No， because most music is still sold unprotected on CDs， people wishing to steal music already can do so. Indeed， scrapping DRM would probably increase online-music sales by reducing confusion and incompatibility. With the leading online store， Apple would benefit most. Mr Jobs’s argument， in short， is transparently self-serving. It also happens to be right.Questions 1-7 Do the following statemets reflect the claims of the writer in Reading Passage 1？Write your answer in Boxes 1-7 on your answer sheet.TRUE if the statement reflets the claims of the writerFALSE if the statement contradicts the claims of the writerNOT GIVEN if it is impossbile to say what the writer thinks about this1.

DRM is a government decree issued with a purpose to protect downloaded music from theft by consumers.3. Lack of standardization in DRM makes songs bought for one kind of music player may not function on another.4. Apple has been criticized by European regulators since it has refused to grant a license FairPlay to other firms.5. All music can be easily played on non-iPod music devices from Sony or Microsoft without too much fiddling.6. Apple depends far more on DRM rather than branding for its dominance of the digital music devices.7.

以下是店铺为大家搜索整理的`雅思考试阅读理解模拟预测试题及答案解析，希望对正在关注的您有所帮助!Alok Jha, science correspondentThursday January 11, 2007The Guardian1. British scientists are preparing to launch trials of a radical new way to fight cancer, which kills tumours by infecting them with viruses like the common cold.2. If successful, virus therapy could eventually form a third pillar alongside radiotherapy and chemotherapy in the standard arsenal against cancer, while avoiding some of the debilitating side-effects.3. Leonard Seymour, a professor of gene therapy at Oxford University, who has been working on the virus therapy with colleagues in London and the US, will lead the trials later this year. Cancer Research UK said yesterday that it was excited by the potential of Prof Seymour's pioneering techniques.4. One of the country's leading geneticists, Prof Seymour has been working with viruses that kill cancer cells directly, while avoiding harm to healthy tissue. "In principle, you've got something which could be many times more effective than regular chemotherapy," he said.5. Cancer-killing viruses exploit the fact that cancer cells suppress the body's local immune system. "If a cancer doesn't do that, the immune system wipes it out. If you can get a virus into a tumour, viruses find them a very good place to be because there's no immune system to stop them replicating. You canregard it as the cancer's Achilles' heel."6. Only a small amount of the virus needs to get to the cancer. "They replicate, you get a million copies in each cell and the cell bursts and they infect the tumour cells adjacent and repeat the process," said Prof Seymour.7. Preliminary research on mice shows that the viruses work well on tumours resistant to standard cancer drugs. "It's an interesting possibility that they may have an advantage in killing drug-resistant tumours, which could be quite different to anything we've had before."8. Researchers have known for some time that viruses can kill tumour cells and some aspects of the work have already been published in scientific journals. American scientists have previously injected viruses directly into tumours but this technique will not work if the cancer is inaccessible or has spread throughout the body.9. Prof Seymour's innovative solution is to mask the virus from the body's immune system, effectively allowing the viruses to do what chemotherapy drugs do - spread through the blood and reach tumours wherever they are. The big hurdle has always been to find a way to deliver viruses to tumours via the bloodstream without the body's immune system destroying them on the way.10. "What we've done is make chemical modifications to the virus to put a polymer coat around it - it's a stealth virus when you inject it," he said.11. After the stealth virus infects the tumour, it replicates, but the copies do not have the chemical modifications. If they escape from the tumour, the copies will be quickly recognised and mopped up by the body's immune system.12. The therapy would be especially useful for secondary cancers, called metastases, which sometimes spread around the body after the first tumour appears. "There's an awful statistic of patients in the west ... with malignant cancers; 75% of them go on to die from metastases," said Prof Seymour.13. Two viruses are likely to be examined in the first clinical trials: adenovirus, which normally causes a cold-like illness, and vaccinia, which causes cowpox and is also used in the vaccine against smallpox. For safety reasons, both will be disabled to make them less pathogenic in the trial, but Prof Seymour said he eventually hopes to use natural viruses.14. The first trials will use uncoated adenovirus and vaccinia and will be delivered locally to liver tumours, in order to establish whether the treatment is safe in humans and what dose of virus will be needed. Several more years of trials will be needed, eventually also on the polymer-coated viruses, before the therapy can be considered for use in the NHS. Though the approach will be examined at first for cancers that do not respond to conventional treatments, Prof Seymour hopes that one day it might be applied to all cancers.(665 words)Questions 1-6Do the following statements agree with the information given in the reading passage? For questions 1-6 write TRUE if the statement agrees with the informationFALSE if the statement contradicts the informationNOT GIVEN if there is no information on this in the passage1.Virus therapy, if successful, has an advantage in eliminating side-effects.2.Cancer Research UK is quite hopeful about ProfessorSeymour’s work on the virus therapy.3.Virus can kill cancer cells and stop them from growing again.4.Cancer’s Achilles’ heel refers to the fact that virus may stay safely in a tumor and replicate.5.To infect the cancer cells, a good deal of viruses should be injected into the tumor.6.Researches on animals indicate that virus could be used asa new way to treat drug-resistant tumors.Question 7-9Based on the reading passage, choose the appropriate letter from A-D for each answer.rmation about researches on viruses killing tumor cells can be found(A) on TV(B) in magazines(C) on internet(D) in newspapers8.To treat tumors spreading out in body, researchers try to(A) change the body’ immune system(B) inject chemotherapy drugs into bloodstream.(C) increase the amount of injection(D) disguise the viruses on the way to tumors.9.When the chemical modified virus in tumor replicates, the copies(A) will soon escape from the tumor and spread out.(B) will be wiped out by the body’s immune system.(C) will be immediately recognized by the researchers.(D) will eventually stop the tumor from spreading out.Questions 10-13Complete the sentences below.

剑桥雅思真题6-阅读Test 4(附答案)
剑桥雅思真题6-阅读Test 4（附答案）Reading Passage 1You should spend about 20 minutes on QUESTIONS 1-13 which are based on Reading Passage 1 below.Doctoring salesPharmaceuticals is one of the most profitable industries in North America. But do the drugs industry’s sales and marketing strategies go too far?A A few months ago Kim Schaefer, sales representative of a major global pharmaceutical company, walked into a medical center in New York to bring information and free samples of her company’s latest products. That day she was lucky - a doctor was available to see her. 'The last rep offered me a trip to Florida. What do you have?’ the physician asked. He was only half Joking.B What was on offer that day was a pair of tickets for a New York musical. But on any given day, what Schaefer can offer Is typical for today's drugs rep - a car trunk Full of promotional gifts and gadgets, a budget that could buy lunches and dinners for a small country, hundreds of free drug samples and the freedom to give a physician $200 to prescribe her new product to the next six patients who fit the drug's profile. And she also has a few $ 1,000 honoraria to offer in exchange for doctors' attendance at her company's next educational lecture.C Selling pharmaceuticals is a daily exercise in ethical Judgment. Salespeople like Schaefer walk the line between the common practice of buying a prospect’s time with a free meal, and bribing doctors to prescribe their drugs. They work In an industry highly criticized for Its sales and marketing practices, but find themselves in the middle of the age-old chicken-or-egg question-businesses won't use strategies that don’t work, so are doctors to blame for the escalating extravagance of pharmaceutical marketing? Or is it the industry's responsibility to decide the boundaries?D The explosion in the sheer number of salespeople in the field-and the amount of funding used to promote their causes - forces close examination of the pressures, influences and relationships between drug reps and doctors. Salespeople provide much-needed Information and education to physicians. In many cases the glossy brochures, article reprints and prescriptions they deliver are primary sources of drug education for healthcare givers. With the huge investment the industry has placed in face-to-face selling, salespeople have essentially become specialists in one drug or group of drugs-a tremendous advantage in getting the attention of busy doctors in need of quick Information.E But the sales push rarely stops in the office. The flashy brochures and pamphlets left by the sales reps are often followed up with meals at expensive restaurants, meetings in warm and sunny places, and an inundation of promotional gadgets. Rarely do patients watch a doctor write with a pen that isn’t emblazoned with a drug's name, or see a nurse use a tablet not bearing a pharmaceutical company's logo. Millions of dollars are spent by pharmaceutical companies on promotional products like coffee mugs, shirts, umbrellas, and golf balls. Money well spent? It’s hard to tell. 'I've been the recipient of golf balls from one company and I use them, but it doesn’t make me prescribe their medicine’, says one doctor, 'I tend to think I’m not influenced by whatthey give me.'F Free samples of new and expensive drugs might be the single most effective way of getting doctors and patients to become loyal to a product. Salespeople hand out hundreds of dollars’ worth of samples each week- $7.2 billion worth of them in one year. Though few comprehensive studies have been conducted, one by the University of Washington Investigated how drug sample availability affected what physicians prescribe. A total of 131 doctors self-reported their prescribing patterns - the conclusion was that the availability of samples led them to dispense and prescribe drugs that differed from their preferred drug choice.G The bottom line is that pharmaceutical companies as a whole invest more in marketing than they do in research and development. And patients are the ones who pay-in the form of sky-rocketing prescription prices - for every pen that's handed out, every free theatre ticket, and every steak dinner eaten. In the end the fact remains that pharmaceutical companies have every right to make a profit and will continue to find new ways to Increase sales. But as the medical world continues to grapple with what's acceptable and what’s not, it is clear that companies must continue to be heavily scrutinized for their sales and marketing strategies.Question 1-7Reading Passage 3 has seven paragraphs, A-G.Choose the correct heading for paragraphs from the list of headings below.Write the correct number, i-x, in boxes 1 - 7 on your answer sheet.1 Paragraph A2 Paragraph B3 Paragraph C4 Paragraph D5 Paragraph E6 Paragraph F7 Paragraph GQuestion 8-13Do the following statements agree with the claims of the writer in Reading Passage 1?In boxes 8-13 on your answer sheet, writeYES if the statement agrees with the informationNO if the statement contradicts the informationNOT GIVEN if there is no information on this in the passage8. Sales representatives like Kim Schaefer work to a very limited budget.9. Kim Schaefer's marketing technique may be open to criticism on moral grounds.10. The information provided by drug companies is of little use to doctors.11. Evidence of drug promotion is clearly visible in the healthcare environment.12. The drug companies may give free drug samples to patients without doctors’ prescriptions.13. It is legitimate for drug companies to make money.Reading Passage 2You should spend about 20 minutes on QUESTIONS 14-26 which are based on Reading Passage 2 below.Do literate women make better mothers?Children in developing countries are healthier and more likely to survive past the age of five when their mothers can read and write. Experts in public health accepted this idea decades ago, but until now no one has been able to show that a woman's ability to read in itself improves her children's chances of survival.Most literate women learnt to read in primary school, and the fact that a woman has had an education may simply indicate her family's wealth or that it values its children more highly. Now a long-term study carried out in Nicaragua has eliminated these factors by showing that teaching reading to poor adult women, who would otherwise have remained illiterate, has a direct effect on their children's health and survival. In 1979, the government of Nicaragua established a number of social programmes, including A National Literacy Crusade. By 1985, about 300,000 illiterate adults from all over the Country, many of whom had never attended primary school, had learnt how to read, write and use numbers.During this period, researchers from the Liverpool School of Tropical Medicine, the Central American Institute of Health in Nicaragua, the National Autonomous University of Nicaragua and the Costa Rican Institute of Health interviewed nearly 3,000 women: some of whom had learn to read as children, some during the literacy crusade and some who had never learnt at all. The women were asked how many children they had given birth to and how many of them had died ininfancy. The research teams also examined the surviving children to find out how well-nourished they were.The investigators' findings were striking. In the late 1970s, the infant mortality rate for the children of illiterate mothers was around 110 deaths per thousand live births. At this point in their lives, those mothers who later went on to learn to read had a similar level of child mortality (105/1000). For women educated in primary school, however, the infant mortality rate was significantly lower, at 80 per thousand.In 1985, after the National Literacy Crusade had ended, the infant mortality figures for those who remained illiterate and for those educated in primary school remained more or less unchanged. For those women who learnt to read through the campaign, the infant mortality rate was 84 per thousand, an impressive 21 points lower than for those women who were still illiterate. The children of the newly-literate mothers were also better nourished than those of women who could not read.Why are the children of literate mothers better off? According to Peter Sandiford of the Liverpool School of Tropical Medicine, no one knows for certain. Child health was not on the curriculum during the women's lessons, so he and his colleagues are looking at other factors. They are working with the same group of 3,000 women, to try to find out whether reading mothers make better use of hospitals and clinics, opt for smaller families, exert more control at home, learn modern childcare techniques more quickly, or whether they merely have more respect for themselves and their children.The Nicaraguan study may have important implications for governments and aid agencies that need to know where to direct their resources. Sandiford says that there is increasing evidence that female education, at any age, is 'an important health intervention in its own right'. The results of the study lend support to the World Bank's recommendation that education budgets in developing countries should be increased, not just to help their economies, but also to improve child health. 'We've known for a long time that maternal education is important,' says John Cleland of the London School of Hygiene and Tropical Medicine，'But we thought that even if we started educating girls today, we'd have to wait a generation for the pay-off. The Nicaraguan study suggests we may be able to bypass that.'Cleland warns that the Nicaraguan crusade was special in many ways, and similar campaigns elsewhere might not work as well. It is notoriously difficult to teach adults skills that do not have an immediate impact on their everyday lives, and many literacy campaigns in other countries have been much less successful. 'The crusade was part of a larger effort to bring a better life to the people,' says Cleland. Replicating these conditions in other countries will be a major challenge for development workers.Question 14-18Complete the summary using the list of words, A-J, below.Write the correct letter, A-J, in boxes 14-18 on your answer sheetNB You may use any letter more than onceThe Nicaraguan National Literacy Crusade aimed to teach large numbers of illiterate14 …………to read and write. Public health experts have known for many years that there is a connection between child health and 15 ………… . However, it has not previously been known whether these two factors were directly linked or not. This question has been investigated by 16 ………… in Nicaragua. As a result, factors such as 17 ………… and attitude to children have been eliminated, and it has been shown that 18 ………… can in itself improve infant health and survival.Question 19-24Do the following statements agree with the claims of the writer in Reading Passage 2?In boxes 19-24 on your answer sheet, writeYES if the statement agrees with the informationNO if the statement contradicts the informationNOT GIVEN if there is no information on this in the passage19. About a thousand of the women interviewed by the researchers had learnt to read when they were children.20. Before the National Literacy Crusade, illiterate women had approximately the same levels of infant mortality as those who had learnt to read in primary school.21. Before and after the National Literacy Crusade, the child mortality rate for the illiterate women stayed at about 110 deaths for each thousand live births.22. The women who had learnt to read through the National Literacy Crusade showed the greatest change in infant mortality levels.23. The women who had learnt to read through the National Literacy Crusade had the lowest rates of child mortality.24. After the National Literacy Crusade, the children of the women who remained illiterate were found to be severely malnourished.Question 25-26Choose TWO letters, A-E.Write the correct letters in boxes 25 and 26 on your answer sheet.Which TWO important implications drawn from the Nicaraguan study are mentioned by the writer of the passage?A. It is better to educate mature women than young girls.B. Similar campaigns in other countries would be equally successful.C. The effects of maternal literacy programmes can be seen very quickly.D. Improving child health can quickly affect a country's economy.E. Money spent on female education will improve child health.Reading Passage 3You should spend about 20 minutes on QUESTIONS 27-40 which are based on Reading Passage 3 below.Persistent bullying is one of the worst experiences a child can face. How can it be prevented? Peter Smith, Professor of Psychology at the University of Sheffield, directed the Sheffield Anti-Bullying Intervention Project, funded by the Department for Education. Here hereports on his findings.A Bullying can take a variety of forms, from the verbal - being taunted or called hurtful names -to the physical - being kicked or shoved - as well as indirect forms, such as being excluded from social groups. A survey I conducted with Irene Whitney found that in British primary schools up to a quarter of pupils reported experience of bullying, which in about one in ten cases was persistent. There was less bullying in secondary schools, with about one in twenty-five suffering persistent bullying, but these cases may be particularly recalcitrant.B Bullying is clearly unpleasant, and can make the child experiencing it feel unworthy and depressed. In extreme cases it can even lead to suicide, though this is thankfully rare. Victimised pupils are more likely to experience difficulties with interpersonal relationships as adults, while children who persistently bully are more likely to grow up to be physically violent, and convicted of anti-social offences.C Until recently, not much was known about the topic, and little help was available to teachers to deal with bullying. Perhaps as a consequence, schools would often deny the problem. There is no bullying at this school has been a common refrain, almost certainly untrue. Fortunately more schools are now saying: There is not much bullying here, but when it occurs we have a clear policy for dealing with it.D Three factors are involved in this change. First is an awareness of the severity of the problem. Second, a number of resources to help tackle bullying have become available in Britain. For example, the Scottish Council for Research in Education produced a package of materials, Action Against Bullying, circulated to all schools in England and Wales as well as in Scotland in summer 1992, with a second pack, Supporting Schools Against Bullying, produced the following year. In Ireland, Guidelines on Countering Bullying Behaviour in Post-Primary Schools was published in 1993. Third, there is evidence that these materials work, and that schools can achieve something. This comes from carefully conducted before and after evaluations of interventions in schools, monitored by a research team. In Norway, after an intervention campaign was introduced nationally, an evaluation of forty-two schools suggested that, over a two-year period, bullying was halved. The Sheffield investigation, which involved sixteen primary schools and seven secondary schools, found that most schools succeeded in reducing bullying.E Evidence suggests that a key step is to develop a policy on bullying, saying clearly what is meant by bullying, and giving explicit guidelines on what will be done if it occurs, what records will be kept, who will be informed, what sanctions will be employed. The policy should be developed through consultation, over a period of time - not just imposed from the head teachersoffice! Pupils, parents and staff should feel they have been involved in the policy, which needs to be disseminated and implemented effectively.Other actions can be taken to back up the policy. There are ways of dealing with the topic through the curriculum, using video, drama and literature. These are useful for raising awareness, and can best be tied in to early phases of development, while the school is starting to discuss the issue of bullying. They are also useful in renewing the policy for new pupils, or revising it in the light of experience. But curriculum work alone may only have short-term effects; it should be an addition to policy work, not a substitute.There are also ways of working with individual pupils, or in small groups. Assertiveness training for pupils who are liable to be victims is worthwhile, and certain approaches to group bullying such as no blame, can be useful in changing the behaviour of bullying pupils without confronting them directly, although other sanctions may be needed for those who continue with persistent bullying.Work in the playground is important, too. One helpful step is to train lunchtime supervisors to distinguish bullying from playful fighting, and help them break up conflicts. Another possibility is to improve the playground environment, so that pupils are less likely to be led into bullying from boredom or frustration.F With these developments, schools can expect that at least the most serious kinds of bullying can largely be prevented. The more effort put in and the wider the whole school involvement, the more substantial the results are likely to be. The reduction in bullying -and the consequent improvement in pupil happiness - is surely a worthwhile objective.Questions 27-30Reading Passage 3 has six sections, A-F.Choose the correct heading for sections A-D from the list of headings below.Write the correct number, i-vii, in boxes 27-30 on your answer sheet.28 Section B29 Section C30 Section DQuestions 31-34Choose the correct letter, A, B, C or D.Write the correct letter in boxes 31-34 on your answer sheet.31 A recent survey found that in British secondary schoolsA there was more bullying than had previously been the case.B there was less bullying than in primary schools.C cases of persistent bullying were very common.D indirect forms of bullying were particularly difficult to deal with.32 Children who are bulliedA are twice as likely to commit suicide as the average person.B find it more difficult to relate to adults.C are less likely to be violent in later life.D may have difficulty forming relationships in later life.33 The writer thinks that the declaration There is no bullying at this schoolA is no longer true in many schools.B was not in fact made by many schools.C reflected the schools lack of concern.D reflected a lack of knowledge and resources.34 What were the findings of research carried out in Norway?A Bullying declined by 50% after an anti-bullying campaign.B Twenty-one schools reduced bullying as a result of an anti-bullying campaign.C Two years is the optimum length for an anti-bullying campaign.D Bullying is a less serious problem in Norway than in the UK.Questions 35-39Complete the summary below.Choose NO MORE THAN TWO WORDS from the passage for each answer.Write your answers in boxes 35-39 on your answer sheet.What steps should schools take to reduce bullying?The most important step is for the school authorities to produce a 35........ which makes the schools attitude towards bullying quite clear.

剑桥雅思阅读7原文(test4)READING PASSAGE 1You should spend about 20 minutes on Questions 1-13, which are based on Reading Passage 1 below.Pulling strings to build pyramidsNo one knows exactly how the pyramids were built. Marcus Chown reckons the answer could be ‘hanging in the air’.The pyramids of Egypt were built more than three thousand years ago, and no one knows how. The conventional picture is that tens of thousands of slaves dragged stones on sledges. But there is no evidence to back this up. Now a Californian software consultant called Maureen Clemmons has suggested that kites might have been involved. While perusing a book on the monuments of Egypt, she noticed a hieroglyph that showed a row of men standing in odd postures. They were holding what looked like ropes that led, via some kind of mechanical system, to a giant bird in the sky. She wondered if perhaps the bird was actually a giant kite, and the men were using it to lift a heavy object.Intrigued, Clemmons contacted Morteza Gharib, aeronautics professor at the California Institute of Technology. He was fascinated by the idea. ‘Coming from Iran, I have a keen interest in Middle Eastern science,’ he says. He too was puzzled by the picture that had sparked Clemmons’s interest. The object in the sky apparently had wings far too short and wide for a bird. ‘The possibility certainly existed that it was a kite,’ he says. And sincehe needed a summer project for his student Emilio Graff, investigating the possibility of using kites as heavy lifters seemed like a good idea.Gharib and Graff set themselves the task of raising a 4.5-metre stone column from horizontal to vertical, using no source of energy except the wind. Their initial calculations and scale-model wind-tunnel experiments convinced them they wouldn’t need a strong wind to lift the 33.5-tonne column. Even a modest force, if sustained over a long time, would do. The key was to use a pulley system that would magnify the applied force. So they rigged up a tent-shaped scaffold directly above the tip of the horizontal column, with pulleys suspended from the scaffold’s apex. The idea was that as one end of the column rose, the base would roll across the ground on a trolley.Earlier this year, the team put Clemmons’s unlikely theory to the test, using a 40-square-metre rectangular nylon sail. The kite lifted the column clean off the ground. ‘We were absolutely stunned,’ Gharib says. ‘The instant the sail opened into the wind, a huge force was generated and the column was raised to the vertical in a mere 40 seconds.’The wind was blowing at a gentle 16 to 20 kilometres an hour, little more than half what they thought would be needed. What they had failed to reckon with was what happened when the kite was opened. ‘There was a huge initial force — five times larger than the steady state force,’ Gharib says. This jerk meant that kites could lift huge weights, Gharib realised. Even a 300-tonne column could have been lifted to the vertical with 40 or so men and four or five sails. So Clemmons was right: the pyramid builders could have used kites to lift massive stones into place. ‘Whether they actually did is another matter,’ Gharib says.There are no pictures showing the construction of the pyramids, so there is no way to tell what really happened. ‘The evidence for using kites to move large stones is no better or worse than the evidence for the brute force method,’ Gh arib says.Indeed, the experiments have left many specialists unconvinced. ‘The evidence for kite-lifting is non-existent,’ says Willeke Wendrich, an associate professor of Egyptology at the University of California, Los Angeles.Others feel there is more of a case for the theory. Harnessing the wind would not have been a problem for accomplished sailors like the Egyptians. And they are known to have used wooden pulleys, which could have been made strong enough to bear the weight of massive blocks of stone. In addition, there is some physical evidence that the ancient Egyptians were interested in flight. A wooden artefact found on the step pyramid at Saqqara looks uncannily like a modern glider. Although it dates from several hundred years after the building of the pyramids, its sophistication suggests that the Egyptians might have been developing ideas of flight for a long time. And other ancient civilisations certainly knew about kites; as early as 1250 BC, the Chinese were using them to deliver messages and dump flaming debris on their foes.The experiments might even have practical uses nowadays. There are plenty of places around the globe where people have no access to heavy machinery, but do know how to deal with wind, sailing and basic mechanical principles. Gharib has already been contacted by a civil engineer in Nicaragua, who wants to put up buildings with adobe roofs supported by concrete arches on a site that heavy equipment can’t reach. His idea is to build the arches horizontally, then lift them into place using kites.‘We’ve given him some design hints,’ says Gharib. ‘We’re just waiting for him to report back.’ So whether they were actually used to build the pyramids or not, it seems that kites may make sensible construction tools in the 21st century AD.Questions 1-7Do the following statements agree with the information given in Reading Passage 1?In boxes 1-7 on your answer sheet, writeTRUE if the statement agrees with the informationFALSE if the statement contradicts the informationNOT GIVEN if there is no information on this1 It is generally believed that large numbers of people were needed to build the pyramids.2 Clemmons found a strange hieroglyph on the wall of an Egyptian monument.3 Gharib had previously done experiments on bird flight.4 Gharib and Graff tested their theory before applying it.5 The success of the actual experiment was due to the high speed of the wind.6 They found that, as the kite flew higher, the wind force got stronger.7 The team decided that it was possible to use kites to raise very heavy stones.Questions 8-13Complete the summary below.Choose NO MORE THAN TWO WORDS from the passage for each answer.Write your answers in boxes 8-13 on your answer sheet.Additional evidence for theory of kite-liftingThe Egyptians had 8.................., which could lift large pieces of9.................., and they knew how to use the energy of the wind from their skill as 10.................. .The discovery on one pyramid of an object which resembled a 11.................. suggests they may have experimented with 12.................. .

The islands’ native inhabitants called this land mass Aleyska, the ‘Great Land’; today, we know it as Alaska.The forty-ninth state to join the United States of America (in 1959), Alaska is fully one-fifth the size of the mainland 48 states combined. It shares, with Canada, the second longest river system in North America and has over half the coastline of the United States. The rivers feed into the Bering Sea and Gulf of Alaska —cold, nutrient-rich waters which support tens of millions of seabirds, and over 400 species of fish, shellfish, crustaceans, and molluscs. Taking advantage of this rich bounty, Alaska’s commercial fisheries have developed into some of the largest in the world.According to the Alaska Department of Fish and Game (ADF&G), A laska’s commercial fisheries landed hundreds of thousands of tonnes of shellfish and herring, and well over a million tonnes of groundfish (cod, sole, perch and pollock) in 2000. The true cultural heart and soul of Alaska’s fisheries,however, is salmon. ‘Salmon,’ notes writer Susan Ewing in The Great Alaska Nature Factbook, ‘pump through Alaska like blood through a heart, bringing rhythmic, circulating nourishment to land, animals and people.’ The ‘predictable abundance of salmon allowed some native cultur es to flourish,’ and ‘dying spawners_feed bears, eagles, other animals, and ultimately the soil itself.’ All five species of Pacific salmon — chinook, or king; chum, or dog; coho, or silver; sockeye, or red; and pink, or humpback —spawn_ in Alaskan waters, and 90% of all Pacific salmon commercially caught in North America are produced there. Indeed, if Alaska was an independent nation, it would be the largest producer of wild salmon in the world. During 2000, commercial catches of Pacific salmon in Alaska exceeded 320,000 tonnes, with an ex-vessel value of over $US260 million.Catches have not always been so healthy. Between 1940 and 1959, overfishing led to crashes in salmon populations so severe that in 1953 Alaska was declared a federal disaster area. With the onset of statehood, however, the State of Alaska took over management of its own fisheries, guided by a state constitution which mandates that Alaska’s natural resources be managed on a sustainable basis. At that time, statewide harvests totalled around 25 million salmon. Over the next few decades average catches steadily increased as a result of this policy of sustainable management, until, during the 1990s, annual harvests were well in excess of 100 million, and on several occasions over 200 million fish.The primary reason for such increases is what is known as ‘In-Season Abundance-Based Management’. There are biologists throughout the state constantly monitoring adult fish as they show up to spawn. The biologists sit in streamsidecounting towers, study sonar, watch from aeroplanes, and talk to fishermen. The salmon season in Alaska is not pre-set. The fishermen know the approximate time of year when they will be allowed to fish, but on any given day, one or more field biologists in a particular area can put a halt to fishing. Even sport fishing can be brought to a halt. It is this management mechanism that has allowed Alaska salmon stocks —and, accordingly, Alaska salmon fisheries — to prosper, even as salmon populations in the rest of the United States are increasingly considered threatened or even endangered.In 1999, the Marine Stewardship Council (MSC)__commissioned a review of the Alaska salmon fishery. The Council, which was founded in 1996, certifies fisheries that meet high environmental standards, enabling them to use a label that recognises their environmental responsibility. The MSC has established a set of criteria by which commercial fisheries can be judged. Recognising the potential benefits of being identified as environmentally responsible, fisheries approach the Council requesting to undergo the certification process. The MSC then appoints a certification committee, composed of a panel of fisheries experts, which gathers information and opinions from fishermen, biologists, government officials, industry representatives, non-governmental organisations and others.Some observers thought the Alaska salmon fisheries would not have any chance of certification when, in the months leading up to MSC’s final decision, salmon runs throughout we stern Alaska completely collapsed. In the Yukon and Kuskokwim rivers, chinook and chum runs were probably the poorest since statehood; subsistence communities throughout the region, who normally have priority over commercial fishing, were devastated.The crisis was completely unexpected, but researchers believe it had nothing to do with impacts of fisheries. Rather, they contend, it was almost certainly the result of climatic shifts, prompted in part by cumulative effects of the el nino/la nina phenomenon on Pacific Ocean temperatures, culminating in a harsh winter in which huge numbers of salmon eggs were frozen. It could have meant the end as far as the certification process was concerned. However, the state reacted quickly, closing down all fisheries, even those necessary for subsistence purposes.In September 2000, MSC announced that the Alaska salmon fisheries qualified for certification. Seven companies producing Alaska salmon were immediately granted permission to display the MSC logo on their products. Certification is for an initial period of five years, with an annual review to ensure that the fishery is continuing to meet the required standards._spawners: fish that have released eggs_ spawn: release eggs__MSC: a joint venture between WWF (World Wildlife Fund) and Unilever, a Dutch-based multi-nationalQuestions 14-20Do the following statements agree with the information given in Reading Passage 2?In boxes 14-20 on your answer sheet, writeTRUE if the statement agrees with the information.FALSE if the statement contradicts the informationNOT GIVEN if there is no information on this14 The inhabitants of the Aleutian islands renamed their islands ‘Aleyska.’15 Alaska’s fisheries are owned by some of the world’s largest companies.16 Life in Alaska is dependent on salmon.17 Ninety per cent of all Pacific salmon caught are sockeye or pink salmon.18 More than 320,000 tonnes of salmon were caught in Alaska in 2000.19 Between 1940 and 1959, there was a sharp decrease in Alaska’s salmon populati on.20 During the 1990s, the average number of salmon caught each year was 100 million.Questions 21-26Complete each sentence with the correct ending, A-K, below.Write the correct letter, A-K, in boxes 21-26 on your answer sheet.21 In Alaska, biologists keep a check on adult fish22 Biologists have the authority23 In-Season Abundance-Based Management has allowed the Alaska salmon fisheries24 The Marine Stewardship Council (MSC) was established25 As a result of the collapse of the salmon runs in 1999, the state decided26 In September 2000, the MSC allowed seven Alaska salmon companiesA to recognize fisheries that care for the environment.B to be successful.C to stop fish from spawning.D to set up environmental protection laws.E to stop people fishing for sport.F to label their products using the MSC logo.G to ensure that fish numbers are sufficient to permit fishing.H to assist the subsistence communities in the region.I to freeze a huge number of salmon eggs.J to deny certification to the Alaska fisheries.K to close down all fisheries.READING PASSAGE 3You should spend about 20 minutes on Questions 27-40, which are based on Reading Passage 3 below.EFFECTS OF NOISEIn general, it is plausible to suppose that we should prefer peace and quiet to noise. And yet most of us have had the experience of having to adjust to sleeping in the mountains or the countryside because it was initially ‘too quiet’, an experience that suggests that humans are capable of adapting to a wide range of noise levels. Research supports this view. For example, Glass and Singer (1972) exposed people to short bursts of very loud noise and then measured their ability to work out problems and their physiological reactions to the noise. The noise was quite disruptive at first, but after about four minutes the subjects were doing just as well on their tasks as control subjects who were not exposed to noise. Their physiological arousal also declined quickly to the same levels as those of the control subjects.But there are limits to adaptation and loud noise becomes more troublesome if the person is required to concentrate on more than one task. For example, high noise levels interfered with the performance of subjects who were required to monitor three dials at a time, a task not unlike that of an aeroplane pilot or an air-traffic controller (Broadbent, 1957). Similarly, noise did not affect a subject’s ability to track a moving line with a steering wheel, but it did interfere with the subject’s ability to repeat numbers while tracking (Finkelman and Glass, 1970).Probably the most significant finding from research on noise is that its predictability is more important than how loud it is. We are much more able to ‘tune out’ chronic background noise, even if it is quite loud, than to work under circumstances with unexpected intrusions of noise. In the Glass and Singer study, in which subjects were exposed to bursts of noise as they worked on a task, some subjects heard loud bursts and others heard soft bursts. For some subjects, the bursts were spaced exactly one minute apart (predictable noise); others heard the same amount of noise overall, but the burstsUnpredictable Noise Predictable Noise AverageLoud noise 40.1 31.8 35.9Soft noise 36.7 27.4 32.1Average 38.4 29.6Table 1: Proofreading Errors and Noiseoccurred at random intervals (unpredictable noise). Subjects reported finding the predictable and unpredictable noise equally annoying, and all subjects performed at about the same level during the noise portion of the experiment. But the different noise conditions had quite different after-effects when the subjects were required to proofread written material under conditions of no noise. As shown in Table 1 the unpredictable noise produced more errors in the later proofreading task than predictable noise; and soft, unpredictable noise actually produced slightly more errors on this task than the loud, predictable noise.Apparently, unpredictable noise produces more fatigue than predictable noise, but it takes a while for this fatigue to take its toll on performance.Predictability is not the only variable that reduces oreliminates the negative effects of noise. Another is control. If the individual knows that he or she can control the noise, this seems to eliminate both its negative effects at the time and its after-effects. This is true even if the individual never actually exercises his or her option to turn the noise off (Glass and Singer, 1972). Just the knowledge that one has control is sufficient.The studies discussed so far exposed people to noise for only short periods and only transient effects were studied. But the major worry about noisy environments is that living day after day with chronic noise may produce serious, lasting effects. One study, suggesting that this worry is a realistic one, compared elementary school pupils who attended schools near Los Angeles’s busiest airport with students who attended schools in quiet neighbourhoods (Cohen et al., 1980). It was found that children from the noisy schools had higher blood pressure and were more easily distracted than those who attended the quiet schools. Moreover, there was no evidence of adaptability to the noise. In fact, the longer the children had attended the noisy schools, the more distractible they became. The effects also seem to be long lasting. A follow-up study showed that children who were moved to less noisy classrooms still showed greater distractibility one year later than students who had always been in the quiet schools (Cohen et al, 1981). It should be noted that the two groups of children had been carefully matched by the investigators so that they were comparable in age, ethnicity, race, and social class.Questions 27-29Choose the correct letter, A, B, C or D.Write the correct letter in boxes 27-29 on your answer sheet.27 The writer suggests that people may have difficultysleeping in the mountains becauseA humans do not prefer peace and quiet to noise.B they may be exposed to short bursts of very strange sounds.C humans prefer to hear a certain amount of noise while they sheep.D they may have adapted to a higher noise level in the city.28 In noise experiments, Glass and Singer found thatA problem-solving is much easier under quiet conditions.B physiological arousal prevents the ability to work.C bursts of noise do not seriously disrupt problem-solving in the long term.D the physiological arousal of control subjects declined quickly.29 Researchers discovered that high noise levels are not likely to interfere with theA successful performance of a single task.B tasks of pilots or air traffic controllers.C ability to repeat numbers while tracking moving lines.D ability to monitor three dials at once.Questions 30-34Complete the summary using the list of words and phrases, A-J, below.Write the correct letter, A-J, in boxes 30-34 on your answer sheet.NB You may use any letter more than once.Glass and Singer (1972) showed that situations in which there is intense noise have less effect on performance than circumstances in which 30..................noise occurs.

剑桥雅思真题15-阅读Test 4（附答案）READING PASSAGE 1You should spend about 20 minutes on Questions 1–13, which are based on Reading Passage 1 below.The return of the huarangoThe arid valleys of southern Peru are welcoming the return of a native plantThe south coast of Peru is a narrow, 2,000-kilometre-long strip of desert squeezed between the Andes and the Pacific Ocean. It is also one of the most fragile ecosystems on Earth. It hardly ever rains there, and the only year-round source of water is located tens of metres below the surface. This is why the huarango tree is so suited to life there: it has the longest roots of any tree in the world. They stretch down 50-80 metres and, as well as sucking up water for the tree, they bring it into the higher subsoil, creating a water source for other plant life.Dr David Beresford-Jones, archaeobotanist at Cambridge University, has been studying the role of the huarango tree in landscape change in the Lower lea Valley in southern Peru. He believes the huarango was key to the ancient people's diet and, because it could reach deep water sources, it allowed local people to withstand years of drought when their other crops failed. But over the centuries huarango trees were gradually replaced with crops. Cutting down native woodland leads to erosion, as there is nothing to keep the soil in place. So when the huarangos go, the land turns into a desert. Nothing grows at all in the Lower lea Valley now.For centuries the huarango tree was vital to the people of the neighbouring Middle lea Valley too. They grew vegetables under it and ate products made from its seed pods. Its leaves and bark were used for herbal remedies, while its branches were used for charcoal for cooking and heating, and its trunk was used to build houses. But now it is disappearing rapidly. The majority of the huarango forests in the valley have already been cleared for fuel and agriculture - initially, these were smallholdings, but now they're huge farms producing crops for the international market.'Of the forests that were here 1,000 years ago, 99 per cent have already gone,' says botanist Oliver Whaley from Kew Gardens in London, who, together with ethnobotanist Dr William Milliken, is running a pioneering project to protect and restore the rapidly disappearing habitat. In order to succeed, Whaley needs to get the local people on board, and that has meant overcoming local prejudices. 'Increasingly aspirational communities think that if you plant food trees in your home or street, it shows you are poor, and still need to grow your own food,' he says. In order to stop the Middle lea Valley going the same way as the Lower lea Valley, Whaley is encouraging locals to love the huarangos again. 'It's a process of cultural resuscitation,' he says. He has already set up a huarango festival to reinstate a sense of pride in their eco-heritage, and has helped local schoolchildren plant thousands of trees.'In order to get people interested in habitat restoration, you need to plant a tree that is useful to them,' says Whaley. So, he has been working with local families to attempt to create a sustainable income from the huarangos by turning their products into foodstuffs. 'Boil up the beans and you get this thick brown syrup like molasses. You can also use it in drinks, soups or stews. ' The pods can be ground into flour to make cakes, and the seeds roasted into a sweet, chocolatey 'coffee'. 'It's packed full of vitamins and minerals, ' Whaley says.And some farmers are already planting huarangos. Alberto Benevides, owner of lea Valley's onlycertified organic farm, which Whaley helped set up, has been planting the tree for 13 years. He produces syrup and flour, and sells these products at an organic farmers' market in Lima. His farm is relatively small and doesn't yet provide him with enough to live on, but he hopes this will change. 'The organic market is growing rapidly in Peru, ' Benevides says. 'I am investing in the future.But even if Whaley can convince the local people to fall in love with the huarango again, there is still the threat of the larger farms. Some of these cut across the forests and break up the corridors that allow the essential movement of mammals, birds and pollen up and down the narrow forest strip. In the hope of counteracting this, he's persuading farmers to let him plant forest corridors on their land. He believes the extra woodland will also benefit the farms by reducing their water usage through a lowering of evaporation and providing a refuge for bio-control insects.'If we can record biodiversity and see how it all works, then we're in a good position to move on from there. Desert habitats can reduce down to very little, ' Whaley explains. 'It's not like a rainforest that needs to have this huge expanse. Life has always been confined to corridors and islands here. If you just have a few trees left, the population can grow up quickly because it's used to exploiting water when it arrives? He sees his project as a model that has the potential to be rolled out across other arid areas around the world. 'If we can do it here, in the most fragile system on Earth, then that's a real message of hope for lots of places, including Africa, where there is drought and they just can't afford to wait for rain.'Questions 1-5Complete the notes below.Choose ONE WORD ONLY from the passage for each answer.Complete the table below.Choose NO MORE THAN TWO WORDS from the passage for each answer.Questions 9-13Do the following statements agree with the information given in Reading Passage 1?In boxes 9-13 on your answer sheet, writeTRUE if the statement agrees with the informationFALSE if the statement contradicts the informationNOT GIVEN if there is no information on this9 Local families have told Whaley about some traditional uses of huarango products.10 Farmer Alberto Benevides is now making a good profit from growing huarangos.11 Whaley needs the co-operation of farmers to help preserve the area's wildlife.12 For Whaley's project to succeed, it needs to be extended over a very large area.13 Whaley has plans to go to Africa to set up a similar project.READING PASSAGE 2You should spend about 20 minutes on Questions 13–26, which are based on Reading Passage 2 below.Silbo Gomero-the whistle ‘language’ of the Canary IslandsLa Gomera is one of the Canary Islands situated in the Atlantic Ocean off the northwest coast of Africa. This small volcanic island is mountainous, with steep rocky slopes and deep, wooded ravines, rising to 1,487 metres at its highest peak. It is also home to the best known of the world's whistle 'languages', a means of transmitting information over long distances which is perfectly adapted to the extreme terrain of the island.This 'language', known as 'Silbo' or 'Silbo Gomero' - from the Spanish word for 'whistle'- is now shedding light on the language-processing abilities of the human brain, according to scientists. Researchers say that Silbo activates parts of the brain normally associated with spoken language, suggesting that the brain is remarkably flexible in its ability to interpret sounds as language.'Science has developed the idea of brain areas that are dedicated to language, and we are starting to understand the scope of signals that can be recognised as language,' says David Corina, co-author of a recent study and associate professor of psychology at the University of Washington in Seattle.Silbo is a substitute for Spanish, with individual words recoded into whistles which have high- and low-frequency tones. A whistler - or silbador - puts a finger in his or her mouth to increase the whistle's pitch, while the other hand can be cupped to adjust the direction of the sound. 'There is much more ambiguity in the whistled signal than in the spoken signal/ explains lead researcher Manuel Carreiras, psychology professor at the University of La Laguna on the Canary island of Tenerife. Because whistled 'words' can be hard to distinguish, silbadores rely on repetition, as well as awareness of context, to make themselves understood.The silbadores of Gomera are traditionally shepherds and other isolated mountain folk, and their novel means of staying in touch allows them to communicate over distances of up to 10 kilometres. Carreiras explains that silbadores are able to pass a surprising amount of information via their whistles. 4In daily life they use whistles to communicate short commands, but any Spanish sentence could be whistled.5 Silbo has proved particularly useful when fires have occurred on the island and rapid communication across large areas has been vital.The study team used neuroimaging equipment to contrast the brain activity of silbadores while listening to whistled and spoken Spanish. Results showed the left temporal lobe of the brain, which is usually associated with spoken language, was engaged during the processing of Silbo. The researchers found that other key regions in the brain's frontal lobe also responded to the whistles, including those activated in response to sign language among deaf people. When the experiments were repeated with non-whistlers, however, activation was observed in all areas of the brain.'Our results provide more evidence about the flexibility of human capacity for language in a variety of forms' Corina says. 'These data suggest that left-hemisphere language regions are uniquely adapted for communicative purposes, independent of the modality of signal. The non-Silbo speakers were not recognising Silbo as a language. They had nothing to grab onto, so multiple areas of their brains were activated?Carreiras says the origins of Silbo Gomero remain obscure, but that indigenous Canary Islanders, who were of North African origin, already had a whistled language when Spain conquered the volcanic islands in the 15th century. Whistled languages survive today in Papua New Guinea, Mexico, Vietnam, Guyana, China, Nepal, Senegal, and a few mountainous pockets in southern Europe. There are thought to be as many as 70 whistled languages still in use, though only 12 have been described and studied scientifically. This form of communication is an adaptation found among cultures where people are often isolated from each other, according to Julien Meyer, a researcher at the Institute of Human Sciences in Lyon, France. 'They are mostly used in mountains or dense forests, ' he says. 'Whistled languages are quite clearly defined and represent an original adaptation of the spoken language for the needs of isolated human groups?But with modern communication technology now widely available, researchers say whistled languages like Silbo are threatened with extinction. With dwindling numbers of Gomera islanders still fluent in the language, Canaries' authorities are taking steps to try to ensure its survival. Since 1999, Silbo Gomero has been taught in all of the island's elementary schools. In addition, locals are seeking assistance from the United Nations Educational, Scientific and Cultural Organization (UNESCO). {The local authorities are trying to get an award from the organisation to declare [Silbo Gomero] as something that should be preserved for humanity,' Carreiras adds.Questions 14-19Do the following statements agree with the information given in Reading Passage 2?In boxes 14-19 on your answer sheet, writeTRUE if the statement agrees with the informationFALSE if the statement contradicts the informationNOT GIVEN if there is no information on this14 La Gomera is the most mountainous of all the Canary Islands.15 Silbo is only appropriate for short and simple messages.16 In the brain-activity study, silbadores and non-whistlers produced different results.17 The Spanish introduced Silbo to the islands in the 15th century.18 There is precise data available regarding all of the whistle languages in existence today.19 The children of Gomera now learn Silbo.Questions 20-26Complete the notes below.Choose ONE WORD ONLY from the passage for each answer.You should spend about 20 minutes on Questions 27–40, which are based on Reading Passage 3 below.Environmental practices of big businessThe environmental practices of big businesses are shaped by a fundamental fact that for many of us offends our sense of justice. Depending on the circumstances, a business may maximize the amount of money it makes, at least in the short term, by damaging the environment and hurting people. That is still the case today for fishermen in an unmanaged fishery without quotas, and for international logging companies with short-term leases on tropical rainforest land in places with corrupt officials and unsophisticated landowners. When government regulation is effective, and when the public is environmentally aware, environmentally clean big businesses may out-compete dirty ones, but the reverse is likely to be true if government regulation is ineffective and if the public doesn't care.It is easy for the rest of us to blame a business for helping itself by hurting other people. But blaming alone is unlikely to produce change. It ignores the fact that businesses are not charities but profit-making companies, and that publicly owned companies with shareholders are under obligation to those shareholders to maximize profits, provided that they do so by legal means. US laws make a company's directors legally liable for something termed 'breach of fiduciary responsibility' if they knowingly manage a company in a way that reduces profits. The car manufacturer Henry Ford was in fact successfully sued by shareholders in 1919 for raising the minimum wage of his workers to $5 per day: the courts declared that, while Ford's humanitarian sentiments about his employees were nice, his business existed to make profits for its stockholders.Our blaming of businesses also ignores the ultimate responsibility of the public for creating the conditions that let a business profit through destructive environmental policies. In the long run, it is the public, either directly or through its politicians, that has the power to make such destructive policies unprofitable and illegal, and to make sustainable environmental policies profitable.The public can do that by suing businesses for harming them, as happened after the Exxon Valdez disaster, in which over 40,000 m3 of oil were spilled off the coast of Alaska. The public may also make their opinion felt by preferring to buy sustainably harvested products; by making employees of companies with poor track records feel ashamed of their company and complain to their own management; by preferring their governments to award valuable contracts to businesses with a good environmental track record; and by pressing their governments to pass and enforce laws and regulations requiring good environmental practices.In turn, big businesses can exert powerful pressure on any suppliers that might ignore public or government pressure. For instance, after the US public became concerned about the spread of a disease known as BSE, which was transmitted to humans through infected meat, the USgovernment's Food and Drug Administration introduced rules demanding that the meat industry abandon practices associated with the risk of the disease spreading. But for five years the meat packers refused to follow these, claiming that they would be too expensive to obey. However, when a major fast-food company then made the same demands after customer purchases of its hamburgers plummeted, the meat industry complied within weeks. The public's task is therefore to identify which links in the supply chain are sensitive to public pressure: for instance, fast-food chains or jewelry stores, but not meat packers or gold miners.Some readers may be disappointed or outraged that I place the ultimate responsibility for business practices harming the public on the public itself. I also believe that the public must accept the necessity for higher prices for products to cover the added costs, if any, of sound environmental practices. My views may seem to ignore the belief that businesses should act in accordance with moral principles even if this leads to a reduction in their profits. But I think we have to recognize that, throughout human history, in all politically complex human societies, government regulation has arisen precisely because it was found that not only did moral principles need to be made explicit, they also needed to be enforced.To me, the conclusion that the public has the ultimate responsibility for the behavior of even the biggest businesses is empowering and hopeful, rather than disappointing. My conclusion is not a moralistic one about who is right or wrong, admirable or selfish, a good guy or a bad guy. In the past, businesses have changed when the public came to expect and require different behavior, to reward businesses for behavior that the public wanted, and to make things difficult for businesses practicing behaviors that the public didn't want. I predict that in the future, just as in the past, changes in public attitudes will be essential for changes in businesses' environmental practices.

Large sample international comparisons of pupils’ attainments since the 1960s have established that not only did Japanese pupils at age13 have better scores of average attainment, but there was alsoa larger proportion of ‘low’ attainers in England, where, incidentally, the variation in attainment scores was much greater. The percentage of Gross National Product spent on education is reasonably similar in the two countries, so how is this higher and more consistent attainment in maths achieved?B Lower secondary schools in Japan cover three school years, from the seventh grade (age 13) to the ninth grade (age 15). Virtually all pupils at this stage attend state schools: only 3 per cent are in the private sector. Schools are usually modern in design, set well back from the road and spacious inside. Classrooms are large and pupils sit at single desks in rows. Lessons last for a standardised 50 minutes and are always followed by a 10-minute break, which gives the pupils a chance to let off steam. Teachers begin with a formal address and mutual bowing, and then concentrate on whole-class teaching.Classes are large — usually about 40 — and are unstreamed. Pupils stay in the same class for all lessons throughout the school and develop considerable class identity and loyalty. Pupils attend the school in their own neighbourhood, which in theory removes ranking by school. In practice in T okyo, because of the relative concentration of schools, there is some competition to get into the ‘better’ school in a particular area.C Traditional ways of teaching form the basis of the lessonand the remarkably quiet classes take their own notes of the points made and the examples demonstrated. Everyone has their own copy of the textbook supplied by the central education authority, Monbusho, as part of the concept of free compulsory education up to the age of 15. These textbooks are, on the whole, small, presumably inexpensive to produce, but well set out and logically developed. (One teacher was particularly keen to introduce colour and pictures into maths textbooks: he felt this would make them more accessible to pupils brought up in a cartoon culture.) Besides approving textbooks, Monbusho also decides the highly centralised national curriculum and how it is to be delivered.D Lessons all follow the same pattern. At the beginning, the pupils put solutions to the homework on the board, then the teachers comment, correct or elaborate as necessary. Pupils mark their own homework: this is an important principle in Japanese schooling as it enables pupils to see where and why they made a mistake, so that these can be avoided in future. No one minds mistakes or ignorance as long as you are prepared to learn from them.After the homework has been discussed, the teacher explains the topic of the lesson, slowly and with a lot of repetition and elaboration. Examples are demonstrated on the board; questions from the textbook are worked through first with the class, and then the class is set questions from the textbook to do individually. Only rarely are supplementary worksheets distributed in a maths class. The impression is that the logical nature of the textbooks and their comprehensive coverage of different types of examples, combined with the relative homogeneity of the class, renders work sheets unnecessary. Atthis point, the teacher would circulate and make sure that all the pupils were coping well.E It is remarkable that large, mixed-ability classes could be kept together for maths throughout all their compulsory schooling from 6 to 15. Teachers say that they give individual help at the end of a lesson or after school, setting extra work if necessary. In observed lessons, any strugglers would be assisted by the teacher or quietly seek help from their neighbour. Carefully fostered class identity makes pupils keen to help each other — anyway, it is in their interests since the class progresses together.This scarcely seems adequate help to enable slow learners to keep up. However, the Japanese attitude towards education runs along the lines of ‘if you work hard enough, you can do almost anything’. Parents are kept closely informed of their children’s progress and will play a part in helping their children to keep up with class, s ending them to ‘Juku’ (private evening tuition) if extra help is needed and encouraging them to work harder. It seems to work, at least for 95 per cent of the school population.F So what are the major contributing factors in the success of maths teaching? Clearly, attitudes are important. Education is valued greatly in Japanese culture; maths is recognised as an important compulsory subject throughout schooling; and the emphasis is on hard work coupled with a focus on accuracy.Other relevant points relate to the supportive attitude of a class towards slower pupils, the lack of competition within a class, and the positive emphasis on learning for oneself and improving one’s own standard. And the view of repetitively boring lessons and learning the facts by heart, which is sometimes quoted in relation to Japanese classes, may be unfair and unjustified. Nopoor maths lessons were observed. They were mainly good and one or two were inspirational.Questions 6-9Do the following statements agree with the claims of the writer in Reading Passage 1?In boxes 6-9 on your answer sheet, writeYES if the statement agrees with the claims of the writerNO if the statement contradicts the claims of the writerNOT GIVEN if it is impossible to say what the writer thinks about this6 There is a wider range of achievement amongst English pupils studying maths than amongst their Japanese counterparts.7 The percentage of Gross National Product spent on education generally reflects the level of attainment in mathematics.8 Private schools in Japan are more modern and spacious than state-run lower secondary schools.9 Teachers mark homework in Japanese schools.Questions 10-13Choose the correct letter, A, B, C or D.Write the correct letter in boxes 10-13 on your answer sheet.10 Maths textbooks in Japanese schools areA cheap for pupils to buyB well organized and adapted to the needs of the pupils.C written to be used in conjunction with TV programmes.D not very popular with many Japanese teachers.11 When a new maths topic is introduced，A students answer questions on the board.B students rely entirely on the textbook.C it is carefully and patiently explained to the students.D it is usual for students to use extra worksheets.12 How do schools deal with students who experience difficulties?A They are given appropriate supplementary tuition.B They are encouraged to copy from other pupils.C They are forced to explain their slow progress.D They are placed in a mixed-ability class.13 Why do Japanese students tend to achieve relatively high rates of success in maths?A It is a compulsory subject in Japan.B They are used to working without help from others.C Much effort is made and correct answers are emphasized.D there is a strong emphasis on repetitive learning.READING PASSAGE 2You should spend about 20 minutes on Questions 14-26, which are based on Reading Passage 2 below.Biological control of pestsThe continuous and reckless use of synthetic chemicals for the control of pests which pose a threat to agricultural crops and human health is proving to be counter-productive. Apart from engendering widespread ecological disorders, pesticides have contributed to the emergence of a new breed of chemical-resistant, highly lethal superbugs.According to a recent study by the Food and Agriculture Organisation (FAO), more than 300 species of agricultural pests have developed resistance to a wide range of potent chemicals. Not to be left behind are the disease-spreading pests, about 100 species of which have become immune to a variety of insecticides now in use.One glaring disadvantage of pesticides’ application is that,while destroying harmful pests, they also wipe out many useful non-targeted organisms, which keep the growth of the pest population in check. This results in what agroecologists call the ‘treadmill syndrome’. Because of their tremendous breeding potential and genetic diversity, many pests are known to withstand synthetic chemicals and bear offspring with a built-in resistance to pesticides.The havoc that the ‘treadmill syndrome’ can bring about is well illustrated by what happened to cotton farmers in Central America. In the early 1940s, basking in the glory of chemical-based intensive agriculture, the farmers avidly took to pesticides as a sure measure to boost crop yield. The insecticide was applied eight times a year in the mid-1940s, rising to 28 in a season in the mid-1950s, following the sudden proliferation of three new varieties of chemical-resistant pests.By the mid-1960s, the situation took an alarming turn with the outbreak of four more new pests, necessitating pesticide spraying to such an extent that 50% of the financial outlay on cotton production was accounted for by pesticides. In the early 1970s, the spraying frequently reached 70 times a season as the farmers were pushed to the wall by the invasion of genetically stronger insect species.Most of the pesticides in the market today remain inadequately tested for properties that cause cancer and mutations as well as for other adverse effects on health, says a study by United States environmental agencies. The United States National Resource Defense Council has found that DDT was the most popular of a long list of dangerous chemicals in use.In the face of the escalating perils from indiscriminate applications of pesticides, a more effective and ecologicallysound strategy of biological control, involving the selective use of natural enemies of the pest population, is fast gaining popularity — though, as yet, it is a new field with limited potential. The advantage of biological control in contrast to other methods is that it provides a relatively low-cost, perpetual control system with a minimum of detrimental side-effects. When handled by experts, bio-control is safe, non-polluting and self-dispersing.The Commonwealth Institute of Biological Control (CIBC) in Bangalore, with its global network of research laboratories and field stations, is one of the most active, non-commercial research agencies engaged in pest control by setting natural predators against parasites. CIBC also serves as a clearing-house for the export and import of biological agents for pest control world-wide.CIBC successfully used a seed-feeding weevil, native to Mexico, to control the obnoxious parthenium weed, known to exert devious influence on agriculture and human health in both India and Australia. Similarly the Hyderabad-based Regional Research Laboratory (RRL), supported by CIBC, is now trying out an Argentinian weevil for the eradication of water hyacinth, another dangerous weed, which has become a nuisance in many parts of the world. According to Mrs Kaiser Jamil of RRL, ‘The Argentinian weevil does not attack any other plant and a pair of adult bugs could destroy the weed in 4-5 days.’ CIBC is also perfecting the technique for breeding parasites that prey on ‘disapene scale’ insects — notorious defoliants of fruit trees in the US and India.How effectively biological control can be pressed into service is proved by the following examples. In the late 1960s, when Sri Lanka’s flouri shing coconut groves were plagued by leaf-mininghispides, a larval parasite imported from Singapore brought the pest under control. A natural predator indigenous to India, Neodumetia sangawani, was found useful in controlling the Rhodes grass-scale insect that was devouring forage grass in many parts of the US. By using Neochetina bruci, a beetle native to Brazil, scientists at Kerala Agricultural University freed a 12-kilometre-long canal from the clutches of the weed Salvinia molesta, popularly called ‘African Payal’ in Kerala. About 30,000 hectares of rice fields in Kerala are infested by this weed.Questions 14-17Choose the correct letter, A, B, C, or D.Write the correct letter in boxes 14-17 on your answer sheet.14 The use of pesticides has contributed toA a change in the way ecologies are classified by agroecologists.B an imbalance in many ecologies around the world .C the prevention of ecological disasters in some parts of the the world .D an increase in the range of ecologies which can be usefully farmed.15 The Food and Agriculture Organisation has counted more than 300 agricultural pests whichA are no longer responding to most pesticides in use.B can be easily controlled through the use of pesticides.C continue to spread disease in a wide range of crops.D may be used as part of bio-control’s replacement of pesticides.16 Cotton farmers in Central America began to use pesticidesA because of an intensive government advertising campaign.B in response to the appearance of new varieties of pest.C as a result of changes in the seasons and the climate.D to ensure more cotton was harvested from each crop.17 By the mid-1960s, cotton farmers in Central America found that pesticidesA were wiping out 50% of the pests plaguing the crops.B were destroying 50% of the crop they were meant to protect.C were causing a 50% increase in the number of new pests reported.D were costing 50% of the total amount they spent on their crops.Questions 18-21Do the following statements agree with the claims of the writer in Reading Passage 2?In boxes 18-21 on your answer sheet, writeYES if the statement agrees with the claims of the writerNo if the statement contradicts the claims of the writerNOT GIVEN if it impossible to say what the write thinks about this18 Disease-spreading pests respond more quickly to pesticides than agricultural pests do.19 A number of pests are now born with an innate immunity to some pesticides.20 Biological control entails using synthetic chemicals to try and change the genetic make-up of the pests’ offspring.21 Bio-control is free from danger under certain circumstances.Questions 22-26Complete each sentence with the correct ending, A-I, below.Write the correct letter, A-I, in boxes 22-26 on your answersheet.22 Disapene scale insects feed on23 Neodumetia sangawani ate24 Leaf-mining hispides blighted25 An Argentinian weevil may be successful in wiping out26 Salvinia molesta plaguesA forage grass.B rice fields.C coconut trees.D fruit trees.E water hyacinth.F parthenium weed.G Brazilian beetles.H grass-scale insects.I larval parasites.READING PASSAGE 3You should spend about 20 minutes on Questions 27-40, which are based on Reading Passage 3 below.Collecting Ant SpecimensCollecting ants can be as simple as picking up stray ones and placing them in a glass jar, or as complicated as completing an exhaustive survey of all species present in an area and estimating their relative abundances. The exact method used will depend on the final purpose of the collections. For taxonomy, or classification, long series, from a single nest, which contain all castes (workers, including majors and minors, and, if present, queens and males) are desirable, to allow the determination of variation within species. For ecological studies, the most important factor is collecting identifiable samples of as many of the different species present as possible. Unfortunately, thesemethods are not always compatible. The taxonomist sometimes overlooks whole species in favour of those groups currently under study, while the ecologist often collects only a limited number of specimens of each species, thus reducing their value for taxonomic investigations.To collect as wide a range of species as possible, several methods must be used. These include hand collecting, using baits to attract the ants, ground litter sampling, and the use of pitfall traps. Hand collecting consists of searching for ants everywhere they are likely to occur. This includes on the ground, under rocks, logs or other objects on the ground, in rotten wood on the ground or on trees, in vegetation, on tree trunks and under bark. When possible, collections should be made from nests or foraging columns and at least 20 to 25 individuals collected. This will ensure that all individuals are of the same species, and so increase their value for detailed studies. Since some species are largely nocturnal, collecting should not be confined to daytime. Specimens are collected using an aspirator (often called a pooter), forceps, a fine, moistened paint brush, or fingers, if the ants are known not to sting. Individual insects are placed in plastic or glass tubes (1.5-3.0 ml capacity for small ants, 5-8 ml for larger ants) containing 75% to 95% ethanol. Plastic tubes with secure tops are better than glass because they are lighter, and do not break as easily if mishandled.Baits can be used to attract and concentrate foragers. This often increases the number of individuals collected and attracts species that are otherwise elusive. Sugars and meats or oils will attract different species and a range should be utilised. These baits can be placed either on the ground or on the trunks of trees or large shrubs. When placed on the ground, baits should besituated on small paper cards or other flat, light-coloured surfaces, or in test-tubes or vials. This makes it easier to spot ants and to capture them before they can escape into the surrounding leaf litter.Many ants are small and forage primarily in the layer of leaves and other debris on the ground. Collecting these species by hand can be difficult. One of the most successful ways to collect them is to gather the leaf litter in which they are foraging and extract the ants from it. This is most commonly done by placing leaf litter on a screen over a large funnel, often under some heat. As the leaf litter dries from above, ants (and other animals) move downward and eventually fall out the bottom and are collected in alcohol placed below the funnel. This method works especially well in rain forests and marshy areas. A method of improving the catch when using a funnel is to sift the leaf litter through a coarse screen before placing it above the funnel. This will concentrate the litter and remove larger leaves and twigs. It will also allow more litter to be sampled when using a limited number of funnels.The pitfall trap is another commonly used tool for collecting ants. A pitfall trap can be any small container placed in the ground with the top level with the surrounding surface and filled with a preservative. Ants are collected when they fall into the trap while foraging. The diameter of the traps can vary from about 18 mm to 10 cm and the number used can vary- from a few to several hundred. The size of the traps used is influenced largely by personal preference (although larger sizes are generally better), while the number will be determined by the study being undertaken. The preservative used is usually ethylene glycol or propylene glycol, as alcohol will evaporate quickly and the trapswill dry out. One advantage of pitfall traps is that they can be used to collect over a period of time with minimal maintenance and intervention. One disadvantage is that some species are not collected as they either avoid the traps or do not commonly encounter them while foraging.Questions 27-30Do the following statements agree with the information given in Reading Passage 3?In boxes 27-30 on your answer sheet, writeTRUE if the statement agrees with the informationFALSE if the statement contradicts the informationNOT GIVEN if there is no information on this27 Taxonomic research involves comparing members of one group of ants.28 New species of ants are frequently identified by taxonomists.29 Range is the key criterion for ecological collections.30 A single collection of ants can generally be used for both taxonomic and ecological purposes.Questions 31-36Classify the following statements as referring toA hand collectingB using baitC sampling ground litterD using a pitfall trapWrite the correct letter, A,B,C or D, in boxes 31-36 on your answer sheet.31 It is preferable to take specimens from groups of ants.32 It is particularly effective for wet habitats.33 It is a good method for species which are hard to find.34 Little time and effort is required.35 Separate containers are used for individual specimens.36 Non-alcoholic preservative should be used.Questions 37-40Label the diagram below.Choose NO MORE THAN TWO WORDS from the passage for each answer.Write your answers in boxes 37-40 on your answer sheet.剑桥雅思阅读8原文参考译文(test4)PASSAGE 1 参考译文：数学崛起之地A.就数学的平均成绩而言，日本的纪录要比英格兰和威尔士好得多。

雅思(阅读)历年真题试卷汇编4(题后含答案及解析)
雅思（阅读）历年真题试卷汇编4(题后含答案及解析) 题型有：1.You should spend about 20 minutes on Questions 1-13 which are based on Reading Passage 1 below.The Mozart EffectA Music has been used for centuries to heal the body. In the Ebers Papyrs(one of the earliest medical documents, circa 1500 B.C.), it was recorded that physicians chanted to heal the sick(Castleman, 1994). In various cultures, we have observed singing as part of healing rituals. In the world of Western medicine, however, using music in medicine lost popularity until the introduction of the radio. Researchers then started to notice that listening to music could have significant physical effects. Therapists noticed music could help calm anxiety and researchers saw that listening to music could cause a drop in blood pressure. In addition to these two areas, music has been used with cancer chemotherapy to reduce nausea, during surgery to reduce stress hormone production, during childbirth, and in stroke recovery(Castleman, 1994 and Westley, 1998). It has been shown to decrease pain as well as enhance the effectiveness of the immune system. In Japan, compilations of music are used as medication, of sorts. For example, if you want to cure a headache or migraine, the album suggested Mendelssohn’s “Spring Song,” Dvorak’s “Humoresque,” or part of George Gershwin’s “An American in Paris”(Campbell, 1998). Music is also being used to assist in learning, in a phenomenon called the Mozart Effect.B Frances H. Rauscher, Ph.D., first demonstrated the correlation between music and learning in an experiment in 1993. His experiments indicated that a 10-minute dose of Mozart could temporarily boost intelligence. Groups of students were given intelligence tests after listening to silence, relaxation tapes, or Mozart’s Sonata for Two Pianos in D Major for a short time. He found that after silence, the average IQ score was no, and after the relaxation tape, scores rose a point. After listening to Mozart, however, the scores jumped to 119(Westley, 1998). Even students who did not like the music still had an increased score on the IQ test. Rauscher hypothesized that “listening to complex, non-repetitive music, like Mozart, may stimulate neural pathways that are important in thinking’’(Castleman, 1994).C The same experiment was repeated on rats by Rauscher and Hong Hua Li from Stanford. Rats also demonstrated enhancement in their intelligence performance. These new studies indicate that rats that were exposed to Mozart showed “increased gene expression of BDNF(a neural growth factor), CREB(a learning and memory compound), and Synapsin I(a synaptic growth protein)” in the brain’s hippocampus, compared with rats in the control group, which heard only white noise(e.g. the whooshing sound of a radio tuned between stations).D How exactly does the Mozart effect work? Researchers are still trying to determine the actual mechanisms for the formation of these enhanced learning pathways. Neuroscientists suspect that music can actually help build and strengthen connections between neurons in the cerebral cortex in a process similar to what occurs in braindevelopment despite its type. When a baby is born, certain connections have already been made —like connections for heartbeat and breathing. As new information is learned and motor skills develop, new neural connections are formed. Neurons that are not used will eventually die while those used repeatedly will form strong connections. Although a large number of these neural connections require experience, they also must occur within a certain time frame. For example, a child born with cataracts cannot develop connections within the visual cortex. If the cataracts are removed by surgery right away, the child’s vision develops normally. However, after the age of 2, if the cataracts are removed, the child will remain blind because those pathways cannot establish themselves.E Music seems to work in the same way. In October of 1997, researchers at the University of Konstanz in Germany found that music actually rewires neural circuits(Begley, 1996). Although some of these circuits are formed for physical skills needed to play an instrument, just listening to music strengthens connection used in higher-order thinking. Listening to music can then be thought of as “exercise”for the brain, improving concentration and enhancing intuition.F If you’re a little skeptical about the claims made by supporters of the Mozart Effect, you’re not alone. Many people accredit the advanced learning of some children who take music lessons to other personality traits, such as motivation and persistence, which is required in all types of learning. There have also been claims of that influencing the results of some experiments.G Furthermore, many people are critical of the role the media had in turning an isolated study into a trend for parents and music educators. After Mozart Effect was published to the public, the sales of Mozart CDs stayed on the top of the hit list for three weeks. In an article by Michael Linton, he wrote that the research that began this phenomenon(the study by researchers at the University of California Irvine)showed only a temporary boost in IQ, which was not significant enough to even last throughout the course of the experiment. Using music to influence intelligence was used in Confucian civilization and Plato alluded to Pythagorean music when he described is ideal state in The Republic. In both of these examples, music did not have caused any overwhelming changes, and the theory eventually died out. Linton also asks, “If Mozart’s Music were able to improve health, why was Mozart himself so frequently sick? If listening to Mozart’s music increases intelligence and encourages spirituality, why aren’t the world’s smartest and most spiritual people Mozart specialists?”Linton raises an interesting point, if the Mozart effect causes such significant changes, why isn’t there more documented evidence?H The “trendiness” of the Mozart Effect may have died out somewhat, but there are still strong supporters(and opponents)of the claims made in 1993. Since that initial experiment, there has not been a surge of supporting evidence. However, many parents, after playing classical music while pregnant or when their children are young, will swear by the Mozart Effect. A classmate of mine once told me that listening to classical music while studying will help with memorization. If we approach this controversy from a scientific aspect, although there has been some evidence that music does increase brain activity, actual improvements in learning and memory have not been adequately demonstrated.Questions 7-5Reading Passage 1 has eight paragraphs A-H.Which paragraph contains thefollowing information?Write the correct letter A-H in boxes 1-5 on your answer sheet.1．A description of how music affects the brain development of infants正确答案：D解析：利用细节信息“the brain development of infants”，可以定位于段落D，其中出现了大量的关于婴儿大脑发育的信息，例如“a child born with cataracts cannot developconnections within the visual cortex…”，所以答案为D。

雅思测试阅读模拟考题和答案(四)The Triumph of UnreasonA.Neoclassical economics is built on the assumption that humans are rational beings who have a clear idea of their best interests and strive to extract maximum benefit (or “utility”，in economist-speak) from any situation.Neoclassical economics assumes that the process of decision-making is rational.But that contradicts growing evidence that decision-making draws on the emotions—even when reason is clearly involved.B.The role of emotions in decisions makes perfect sense.For situations met frequently in the past，such as obtaining food and mates，and confronting or fleeing from threats，the neural mechanisms required to weigh up the pros and cons will have been honed by evolution to produce an optimal outcome.Since emotion is the mechanism by which animals are prodded towards such outcomes，evolutionary and economic theory predict thesame practical consequences for utility in these cases.But does this still apply when the ancestral machinery has to respond to the stimuli of urban modernity?C.One of the people who thinks that it does not is George Loewenstein，an economist at Carnegie Mellon University，in Pittsburgh.In particular，he suspects that modern shopping has subverted the decision-making machinery in a way that encourages people to run up debt.To prove the point he has teamed up with two psychologists，Brian Knutson of Stanford University and Drazen Prelec of the Massachusetts Institute of Technology，to look at what happens in the brain when it is deciding what to buy.D.In a study，the three researchers asked 26 volunteers to decide whether to buy a series of products such as a box of chocolates or a DVD of the television show that were flashed on a computer screen one after another.In each round of the task，the researchers first presented the product and then its price，with each step lasting four seconds.In the final stage，which also lasted four seconds，they asked the volunteers to makeup their minds.While the volunteers were taking part in the experiment，the researchers scanned their brains using a technique called functional magnetic resonance imaging (fMRI).This measures blood flow and oxygen consumption in the brain，as an indication of its activity.E.The researchers found that different parts of the brain were involved at different stages of the test.The nucleus accumbens was the most active part when a product was being displayed.Moreover，the level of its activity correlated with the reported desirability of the product in question.F.When the price appeared，however，fMRI reported more activity in other parts of the brain.Excessively high prices increased activity in the insular cortex，a brain region linked to expectations of pain，monetary loss and the viewing of upsetting pictures.The researchers also found greater activity in this region of the brain when the subject decided not to purchase an item.G.Price information activated the medial prefrontal cortex，too.This part of the brain isinvolved in rational calculation.In the experiment its activity seemed to correlate with a volunteer’s reaction to both product and price，rather than to price alone.Thus，the sense of a good bargain evoked higher activity levels in the medial prefrontal cortex，and this often preceded a decision to buy.H.People’s shopping behaviour therefore seems to have piggy-backed on old neural circuits evolved for anticipation of reward and the avoidance of hazards.What Dr Loewenstein found interesting was the separation of the assessment of the product (which seems to be associated with the nucleus accumbens) from the assessment of its price (associated with the insular cortex)，even though the two are then synthesised in the prefrontal cortex.His hypothesis is that rather than weighing the present good against future alternatives，as orthodox economics suggests happens，people actually balance the immediate pleasure of the prospective possession of a product with the immediate pain of paying for it. I.That makes perfect sense as an evolved mechanism for trading.If one useful object is being traded for another (hard cash in moderntime)，the future utility of what is being given up is embedded in the object being traded.Emotion is as capable of assigning such a value as reason.Buying on credit，though，may be different.The abstract nature of credit cards，coupled with the deferment of payment that they promise，may modulate the “con” side of the calculation in favour of the “pro”.J.Whether it actually does so will be the subject of further experiments that the three researchers are now designing.These will test whether people with distinctly different spending behaviour，such as miserliness and extravagance，experience different amounts of pain in response to prices.They will also assess whether，in the same individuals，buying with credit cards eases the pain compared with paying by cash.If they find that it does，then credit cards may have to join the list of things such as fatty and sugary foods，and recreational drugs，that subvert human instincts in ways that seem pleasurable at the time but can have a long and malign aftertaste.Notes to Reading Passage 11.the nucleus accumbens，the insular cortex，and the medial prefrontal cortex:大脑的不同部位 (皮层，皮质等)e.g.cerebellar cortex 小脑皮层cerebral cortex 大脑皮层2.hone:珩磨，磨快，磨练，训练使……更完美或有效.3.subvert:毁灭，破坏;摧毁：4.piggyback：骑在肩上;在肩上骑5.deferment:推迟、延迟、分期付款6.aftertaste:余味，回味事情或经历结束后的感觉，特指令人不快的感觉Questions 1-6Do the following statemets reflect the claims of the writer in Reading Passage 1?Write your answer in Boxes 1-6 on your answer sheet.TRUE if the statement reflets the claims of the writerFALSE if the statement contradicts the claims ofthe writerNOT GIVEN if it is possbile to say what the writer thinks about this1.The belief of neoclassical economics does not accord with the increasing evidence that humans make use of the emotions to make decisions.2.Animals are urged by emotion to strive for an optimal outcomes or extract maximum utility from any situation.3.George Loewenstein thinks that modern ways of shopping tend to allow people to accumulate their debts.4.The more active the nucleus accumens was，the stronger the desire of people for the product in question became.5.The prefrontal cortex of the human brain is linked to monetary loss and the viewing of upsetting pictures.6.When the activity in nucleus accumbens was increased by the sense of a good bargain，people tended to purchase coffee.Questions 7-9Choose the appropriate letters A-D and write them in boxes 7-9 on your answe sheet.7.Which of the following statements about orthodox economics is true?A.The process which people make their decisions is rational.B.People have a clear idea of their best interests in any situation.C.Humans make judgement on the basis of reason rather then emotion.D.People weigh the present good against future alternatives in shopping.8.The word “miserliness” in line 3 of Paragraph J means__________.A.people’s behavior of buying luxurious goodsB.people’s behavior of buying very special itemsC.people’s behavior of being very mean in shoppingD.people’s behavior of being very generous in shopping9.The three researchers are now designing thefuture experiments，which testA.whether people with very different spending behaviour experience different amounts of pain in response to products.B.whether buying an item with credit cards eases the pain of the same individuals compared with paying for it by cash.C.whether the abstract nature of credit cards may modulate the “con” side of the calculation in favour of the “pro”.D.whether the credit cards may subvert human instincts in ways that seem pleasurable but with a terrible effect.Questions 10-13Complete the notes below.Choose NO MORE THAN THREE WORDS from Reading Passage 1 for each answer.Write your answers in boxes 10-13 on your answer sheet.To find what happens in the brain of humans when it is deciding things to buy，George Loewenstein and his co-researchers did an experiment by using thetechnique of fMRI.They found that different parts of the brain were invloved in the process.The activity in …10… was greatly increased with the displaying of certain product.The great activity was found in the insular cortex when …11…and the subject decided not to buy a product.The activity of the medial prefrontal cortex seemed to associate withboth …12…i nformaiton.What interested Dr Loewenstein was the …13… of the assessment of the product and its price in different parts of the brain.
